Development of domain specific impulse-control (DSIC) measure Yoon, Hee Jun Roy 2025-08-18 Roberts, Brent W Roberts, Brent W Napolitano, Christopher Briley, D.A. Zhang, Bo Hankin, Benjamin Impulse Control, Bifactor Model, Personality Development, Factor Analysis, Predictive Analysis eng Impulse control is a well-established predictor of important life outcomes, including health, academic performance, and workplace success. However, traditional measures often conflate distinct psychological processes by failing to distinguish between the urge to act (impulse) and the ability to regulate that urge (control), and by neglecting the contextual specificity of different impulse domains. This dissertation introduces and validates a novel Domain-Specific Impulse-Control (DSIC) measure that differentiates impulse and control across eight behavioral domains: smartphone use, buying, eating, alcohol use, drug use, smoking, sex, and gambling. Across seven diverse samples (N ≈ 2,500), including samples with elevated impulse-control concerns, structural equation modeling was used to test multiple factor structures. The findings supported a bifactor model in which both general and domain-specific factors of impulse and control explained unique variance. Domain-specific DSIC scores showed distinct associations with personality traits, health behaviors, and clinical outcomes. Additionally, developmental analyses across the lifespan revealed that age was equally associated with changes in impulses and controls. These findings advance the conceptualization of impulse control as a multidimensional and context-sensitive construct and offer a foundation for more precise assessment and targeted interventions. 2025-12 Thesis https://hdl.handle.net/2142/132612 Copyright 2025 Hee Jun Yoon Psychology Psychology University of Illinois Urbana-Champaign Ph.D. Dissertation
